Description

Technical Field

[0001] The utility model belongs to the technical field of water supply and drainage engineering, and particularly relates to a flow splitting device for water supply and drainage engineering. Background Technique

[0002] In the water supply and drainage engineering, multiple flow splitting devices for splitting are connected to the main drainage pipe. A common flow splitting device is a flow splitting pipe. After retrieval, the patent with the application number 202122630594.2 discloses a flow splitting device for water supply and drainage engineering, including a main drainage pipe. A plurality of connecting pipes are uniformly communicated with the side wall of the main drainage pipe. A connecting flange A is sleeved on the outer periphery of each connecting pipe far away from the main drainage pipe. A flow splitting pipe is arranged on one side of each connecting pipe far away from the main drainage pipe. A connecting flange B matching with the connecting flange A is fixedly sleeved on the outer periphery of the flow splitting pipe close to the corresponding connecting pipe. A connecting mechanism is sleeved on the outer peripheries of the connecting flange A and the connecting flange B. A switch valve is arranged on each flow splitting pipe.

[0003] However, during the actual use process, the applicant found that when installing the flow splitting pipe onto the main drainage pipe, it is necessary for personnel to first align the connecting flange B connected to the flow splitting pipe with the connecting flange A on the connecting pipe, and attach the connecting flange B to the outer wall of the connecting flange A. Then, the half hoop A and the half hoop B are sleeved on the outer peripheries of the connecting flange A and the connecting flange B. Next, the threaded rod is passed through the insertion slots on the two fixing seats and then the first nut is tightened. Finally, the adjusting screw is driven to rotate by turning the turning rod, and the arc-shaped pressing block is pushed by the adjusting screw, so that the arc-shaped pressing block can press the connecting flange A and the connecting flange B sleeved in the half hoop A and the half hoop B. Repeating the above operations multiple times in this way can complete the installation of multiple flow splitting pipes onto the main drainage pipe, but the operation is still not convenient enough. In view of this, we propose a flow splitting device for water supply and drainage engineering. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model relates to a flow splitting device for water supply and drainage engineering, which comprises a main drainage pipeline.

[0020] Please refer to Figures 1 - 3 As shown, the present utility model provides a technical solution:

[0021] A flow splitting device for water supply and drainage engineering, including a main drainage pipe 1. A rectangular seat 2 is fixedly sleeved outside the main drainage pipe 1. Connecting branch pipes 11 are fixedly arranged side by side on the side wall of the main drainage pipe 1. The front end of the connecting branch pipe 11 extends outside the rectangular seat 2 and is fixedly connected to a connecting seat 4. A chute 41 is opened at the top of the connecting seat 4. A slot 42 is opened on the connecting seat 4 behind the chute 41. The bottom of the chute 41 is flush with the bottom of the slot 42. A water valve 3 is fixedly sleeved on the connecting branch pipe 11. The front side of the connecting seat 4 is movably connected to a pressing seat 7 through a guide rod 6. A screw rod 8 is threaded through the middle of the pressing seat 7. There are two guide rods 6 on both sides of the screw rod 8. The rear end of the guide rod 6 is fixedly connected to the rectangular seat 2. The front end of the guide rod 6 movably penetrates through the pressing seat 7. The rear end of the screw rod 8 is rotatably connected to the rectangular seat 2 through a bearing. A rotating disc 81 is fixedly sleeved on the front end of the screw rod 8. A placement groove 71 is opened at the top of the pressing seat 7. A flow splitting pipe 5 is placed in the placement groove 71. A connecting block 51 is fixedly arranged at the rear end of the flow splitting pipe 5. The connecting block 51 is slidably matched with the chute 41. The rear end of the connecting block 51 is inserted into the slot 42. A sealing gasket 53 is fixedly arranged at the rear end of the connecting block 51. The sealing gasket 53 abuts between the connecting seat 4 and the connecting block 51. Abutting ears 52 are symmetrically and fixedly arranged on the outer wall of the flow splitting pipe 5 in front of the connecting block 51. The rear side of the pressing seat 7 abuts against the abutting ears 52. By aligning the connecting block 51 and sliding it into the bottom of the chute 41, then rotating the screw rod 8 to drive the pressing seat 7 to move backward, and pushing the flow splitting pipe 5 to move backward through the pressing seat 7, so that the connecting block 51 is inserted into the slot 42, the quick connection between the main drainage pipe 1 and the flow splitting pipe 5 can be realized, and the operation is convenient. When connecting the main drainage pipe 1 and the flow splitting pipe 5, one by one, align the connecting block 51 at the rear end of the flow splitting pipe 5 and slide it into the bottom of the corresponding chute 41, and place the flow splitting pipe 5 in the corresponding placement groove 71. Then manually rotate the rotating disc 81 clockwise to drive the screw rod 8 to rotate. The rotation of the screw rod 8 can drive the pressing seat 7 to move backward along the guide rod 6, and push the abutting ears 52 through the pressing seat 7 to drive the flow splitting pipe 5 to move backward, so that the connecting block 51 is inserted into the slot 42. At this time, the sealing gasket 53 can abut between the connecting seat 4 and the connecting block 51 to seal the connection between the connecting block 51 and the connecting seat 4, and the quick connection between the main drainage pipe 1 and the flow splitting pipe 5 can be realized. Operating the above steps in reverse can quickly disassemble the flow splitting pipe 5 and the main drainage pipe 1.

[0022] A locknut 9 is screwed onto the front end of the guide rod 6. An external thread portion 61 is provided at the front end of the guide rod 6. The locknut 9 is in threaded engagement with the external thread portion 61. The locknut 9 abuts against the pressing seat 7. By tightening the locknut 9, the position of the pressing seat 7 can be further locked, preventing the screw 8 from rotating and causing the connection between the pressing seat 7 and the abutting ear 52 to become loose, and further ensuring the sealed connection between the connecting block 51 and the connecting seat 4. After inserting the connecting block 51 into the slot 42, finally, a wrench can be used to tighten the locknut 9 to further lock the pressing seat 7.

[0023] Working principle: When in use, when connecting the main drainage pipe 1 and the diversion pipe 5, one by one, the connecting block 51 at the rear end of the diversion pipe 5 is aligned and slid into the bottom of the corresponding chute 41, and the diversion pipe 5 is placed in the corresponding placement groove 71. Then, manually rotate the rotating disk 81 clockwise to drive the screw 8 to rotate. The rotation of the screw 8 can drive the pressing seat 7 to move backward along the guide rod 6, and through the pressing seat 7, the abutting ear 52 is pushed to drive the diversion pipe 5 to move backward, so that the connecting block 51 is inserted into the slot 42. At this time, the sealing gasket 53 can abut between the connecting seat 4 and the connecting block 51 to seal the connection between the connecting block 51 and the connecting seat 4, thus realizing the quick connection of the main drainage pipe 1 and the diversion pipe 5. After inserting the connecting block 51 into the slot 42, finally, a wrench can be used to tighten the locknut 9 to further lock the pressing seat 7. By operating the above steps in reverse, the diversion pipe 5 and the main drainage pipe 1 can be quickly disassembled.
